Our take: The New 5KU 7mm Ball Bearing Bushings are a great upgrade, especially if you are installing a high speed gear set. These Ball Bearing Bushings will fit in any 7mm gearbox. These are a must have if you plan on upgrading you spring, gear set, or anything else that may put excessive strain on your gearbox. These finely crafted 5KU Ball Bearing Bushings help reduce unnecessary friction and wear inside your gearbox. These bushings are an excellent balance between quality, durability, and performance.
- Extremely durable with high build quality
- Ready to use right out of the box
- Should fit in most 7mm Gearbox AEGs
